Small Intestinal Bacterial Overgrowth (SIBO) is associated with symptoms such as bloating, gas, diarrhea, constipation, abdominal pain, and dyspepsia, and is linked to conditions like IBS, IBD, Celiac Disease, diabetes, fibromyalgia, rosacea, Parkinson’s disease, and obesity. Risk factors include intestinal motility disorders, chronic pancreatitis, structural abnormalities, gastroenteritis, immunocompromise, reduced digestive secretions (e.g., with PPI use), and ileocecal valve dysfunction. If left untreated, SIBO can result in complications such as malabsorption and leaky gut.
